The purpose of this study is to determine the optimal size of a cylindrical buoy based on wave characteristics: wavelength, wave amplitude, wave velocity, and other factors. Waves are classified into long-period swell waves and short-period lippers. A lipper can provide ripple energy to a wave energy converter, this process can easily cause instability of the energy system, therefore a skirt design can be adopted to increase the cylindrical buoy׳s damping and to decrease the effect of the ripple energy source. A swell wave produces a dynamic and steady force on the cylindrical buoy, providing a stable energy source, and can be used to judge whether the converter can achieve the design value of the expected energy by capturing the periodic average potential energy.

Abstract

The purpose of this study is to determine the optimal size of a cylindrical buoy based on wave characteristics: wavelength, wave amplitude, wave velocity, and other factors. Waves are classified into long-period swell waves and short-period lippers. A lipper can provide ripple energy to a wave energy converter, this process can easily cause instability of the energy system, therefore a skirt design can be adopted to increase the cylindrical buoy׳s damping and to decrease the effect of the ripple energy source. A swell wave produces a dynamic and steady force on the cylindrical buoy, providing a stable energy source, and can be used to judge whether the converter can achieve the design value of the expected energy by capturing the periodic average potential energy.
